Treating Rolling Acne Scars

Save

Unlike a shallow blemish mark, a rolling acne scar has structure underneath it: a strand of scar tissue pulling the skin down. Treatment that ignores that tether — a peel, a serum, a single laser pass — tends to disappoint, which is why dermatologists usually build a plan around several techniques.

What Actually Works for Rolling Acne Scars?

Rolling acne scars respond best to treatments that address the fibrous band tethering the scar to deeper tissue, not just treatments that resurface the surface. Subcision, energy-based devices like microneedling, and — for some scars — filler placement are the options with the most direct mechanism, and the strongest results tend to come from combining more than one 1.

No single treatment reliably erases rolling scars; the honest goal is meaningful softening of depth and shadow, achieved gradually across a series of sessions. A candid acne scar treatment comparison across modalities, rather than a single trending device, is the more useful starting point for deciding what to try first.

Why Rolling Scars Need a Different Approach

Rolling scars form when strands of scar tissue, laid down during acne's inflammatory phase, pull the overlying skin down and anchor it to structures underneath. That tethering is what gives rolling scars their sloped, undulating edges, distinct from the punched-out walls of a boxcar scar or the narrow depth of an ice-pick scar, and understanding acne scar types is the first step toward choosing a treatment that actually matches the mechanism.

A treatment that only resurfaces the skin's surface — a superficial peel, for instance — can't release that underlying tether, which is why rolling scars often persist despite a skincare routine that genuinely helps active acne. The tissue causing the depression sits below where topical products reach.

Subcision: Releasing the Tether Underneath

Subcision uses a needle or blunt cannula inserted under the skin to physically cut the fibrous band anchoring a rolling scar to deeper tissue, allowing the depressed skin to lift as it heals. It's one of the few treatments that directly targets the mechanism causing rolling scars, rather than just resurfacing around them 1.

The procedure is typically done under local numbing, causes bruising and swelling for several days to about a week, and is often repeated or paired with another modality like filler or microneedling for a fuller result. Anyone considering subcision for rolling acne scars is usually evaluated first to confirm the scar is genuinely tethered rather than simply shallow.

Microneedling and Energy-Based Devices

Microneedling creates controlled micro-injuries that stimulate collagen production in the dermis, and some devices add radiofrequency energy to intensify that effect; both are reviewed among the modalities with evidence for atrophic scar improvement, though the evidence quality across the board is still considered limited 1.

These treatments work gradually across a series of sessions rather than in one visit, and tend to suit shallower rolling scars better than deep, tightly tethered ones, where subcision or a combination approach is more likely to be recommended.

Fillers, Peels, and Fractional Lasers

Dermal filler injected directly under a rolling scar can physically lift the depression, offering a faster, visible change than most other options, though the effect is temporary and fades as the filler is absorbed. Fillers for acne scars are sometimes used as a bridge before a more permanent treatment, or ahead of a single event.

Fractional lasers create a grid of microscopic treatment zones that stimulate resurfacing and remodeling; fractional laser resurfacing acne scars can help blend the surrounding skin texture, particularly when paired with subcision for scars that are also tethered. Chemical peels and dermabrasion appear in the same review of options but are generally considered better suited to shallow scarring or as an adjunct than as a primary treatment for a deep rolling scar 1.

Should Active Acne Be Treated First?

Most dermatologists address active, inflammatory acne before starting scar treatment, since new breakouts create new scars and can undermine months of work. The AAD's acne guideline lays out a ladder from topical retinoids and benzoyl peroxide, through oral antibiotics, to isotretinoin for severe or scarring disease 2.

For adult women whose acne is hormonally driven and hasn't responded to standard topical or oral options, a placebo-controlled trial found that oral spironolactone improved acne severity, giving another route to control before scar revision begins 3. Getting active acne stable, typically for several months, before booking scar treatment is the more common sequence.

Rolling Scars vs Boxcar Scars: Different Treatment Priorities

Rolling and boxcar scars often appear together on the same face, but they don't respond to identical treatment plans. Rolling scars need the underlying tether addressed, while treating boxcar scars usually focuses more on the sharp, punched-out edges, through resurfacing, subcision if there's some tethering, or, for very shallow boxcar scars, a technique that raises the base directly.

A dermatologist mapping out a treatment plan typically treats a mix of scar types with a mix of techniques in the same series, rather than picking one device and expecting it to address everything on the face.

What Should a Consultation Cover?

A dermatologist evaluating rolling scars typically maps the face by scar type and depth first, since most people have a mix of rolling, boxcar, and sometimes ice-pick scarring rather than one uniform pattern. That mapping is what determines whether subcision, an energy-based device, filler, or some combination makes sense for a particular area, rather than applying one technique across the whole face.

Skin tone, a history of keloid or hypertrophic scarring, and how active the acne still is all factor into which techniques are offered first. Bringing a realistic goal into that conversation — meaningful softening rather than complete erasure — tends to produce a plan that's easier to stick with across the months a real course of treatment takes. Photos taken under consistent lighting before starting are also a common way to track gradual change that's easy to miss day to day in the mirror, since scar softening tends to happen slowly enough that memory alone isn't a reliable measure.

Common questions

No single treatment is most effective for every rolling scar; the strongest results generally come from combining subcision, which releases the tethering band, with an energy-based device or filler that addresses the remaining depression. A treatment plan built around one scar's specific depth and tethering, not a single trending device, tends to perform better.

The area is numbed beforehand, so most people feel pressure rather than sharp pain during the procedure itself. Bruising, swelling, and tenderness for several days to about a week afterward are more noticeable than pain during the session, and makeup can usually cover residual bruising after the first day or two.

Most approaches require a series of sessions spaced weeks apart rather than a single visit, and visible change tends to build gradually as collagen remodels over months. A realistic timeline runs from several months to closer to a year for a full course, depending on scar depth and the combination of treatments used.

Complete removal isn't a realistic goal for most rolling scars; the honest aim is meaningful softening of depth and shadow so the scarring is less noticeable, not scarless skin. People considering treatment are better served by a plan built around that expectation than one promising full erasure.

Most dermatologists recommend getting active, inflammatory acne under control first, since new breakouts can produce new scars during the same window scar treatment is meant to improve. Stabilizing acne for several months before starting scar revision is the more common sequence.

Subcision physically cuts the fibrous band tethering a scar to deeper tissue, addressing the structural cause directly. Microneedling instead triggers a wound-healing response that gradually builds collagen under the scar without cutting anything. The two are often combined, since they work through different mechanisms.

When to Call Your Dermatologist After Scar Treatment

  • —Spreading redness, warmth, or fever after a procedure like subcision or microneedling
  • —A lump or firm area that develops under the skin at an injection or subcision site
  • —Pus or a wound that isn't healing days after treatment

This article describes cosmetic dermatology treatment options in general terms. It is not a substitute for an in-person evaluation, since the right combination of treatments depends on an individual's scar depth, skin type, and treatment history.
